Phrenic Sparing Shoulder Block: A Case Report

Abstract

Interscalene block is used for shoulder surgeries however it almost always results in phrenic nerve palsy1,2. Some anaesthesiologists have described careful ultrasound guided low volume (5mls only) of local anesthetic interscalene block which does not cause hemidiaphragmatic paresis3. However we present to you a case where we implied a recently described technique of phrenic sparing involving a combination of oblique infraclavicular brachial plexus block with subomohyoid suprascapular nerve block.
